I thought the material was well-presented and comprehensible, though it is far outside of my normal area of expertise. I do think there were two weaknesses. One is that the section on wine was brief. The author admitted this and explained that it was because there is so much other information on wine out there, but it still seems like there could have been some useful information that would be helpful for working with customers to figure out what they want. Also the recipes section was very expansive, but I think a smaller section going over which recipes would be more important--like here are the classics, the basics--something like that.
